I'd be much more in favour of a rule requiring the drafting of oldtime players. Some of the teams in the first draft didn't have anybody that played earlier than the 70's, and few that played then.

If each team had to have one player from: Europe, WHA, pre-WWII, pre-67 expansion, etc., they might have to find out who "Cyclone" Taylor is and what kind of player he was.

You then run into the problem of the Bobby Hull, would he be WHA, or an NHL player. I like it this way, as one has a better chance of finding the diamond in the rough in terms of European players, and players who never would have been thought of otherwise.
